| titleOfInvention | Method for realizing multimode quasi-phase matching four-wave mixing in multimode waveguide |
| abstract | The invention discloses a method for realizing multimode quasi-phase matching four-wave mixing in multimode waveguide. The method comprises the steps of firstly determining target signal light wavelength of a four-wave mixing process corresponding to a fundamental mode and a high-order mode, then simulating eigenmodes of straight waveguides with different widths by using simulation software, then calculating to obtain a relation curve of the width of the straight waveguides and phase mismatch amount in the four-wave mixing process corresponding to the fundamental mode and the high-order mode respectively, then determining the width of the straight waveguides by using a multimode phase mismatch amount equation provided by the invention, determining the length of the straight waveguides by using the relation between the length of the straight waveguides and the phase mismatch amount, and finally realizing quasi-phase matching of the four-wave mixing process of the fundamental mode and the high-order mode in the multimode waveguides. The invention takes silicon waveguide as an example to carry out simulation calculation, and the result shows that high-efficiency multimode wavelength conversion can be realized in the range covering the whole C wave band and most L wave bands, thereby overcoming the problem of narrow conversion bandwidth in the conventional multimode wavelength conversion research. |
